Definitions
- the invention relates to a roll stand with two rolls forming a roll gap, which Drive spindles can be driven by their own drive motors, in particular four-high scaffolding, a drive train with a toothed clutch for each roller combined with another articulated coupling.
- a roll stand in which the rolls each have a first tooth coupling with a first shaft and via a second tooth coupling with a Connection shaft and further via a universal joint with a drive shaft and another Universal joint is connected to a drive motor or another drive shaft.
- the Connecting shafts are in an adjustable guide in a parallel arrangement stored.
- relatively large angles must be taken up by the toothed couplings be, because there must be a sufficiently large distance between the Connecting shafts arranged universal joints can be created. This significantly increases the wear of the tooth clutches.
- Another disadvantage of the known roll stand is to see that the distance between the motor and the roll stand is very large, which is a space-consuming drive arrangement results. This also results in a too soft one Torque transmission from the drive motors to the work rolls.
- a roll stand of the type described in the opening paragraph is known is designed similar to the rolling stand described in JP-A-60-37205. Both rollers are each via a tooth coupling with a first shaft and a larger angular one Deviating joint coupling, such as a universal joint, with a cardan shaft and another such articulated coupling, each with a drive motor or gear connected.
- Each drive train is thus formed by two cardan shafts, whereby due to the large space-requiring articulated couplings for larger angular ones Recesses a large distance between the motor and roll stand results in what with Disadvantage of a soft torque transmission from the drive motors to the Work rolls.
- the invention aims at avoiding these disadvantages and difficulties and presents itself the task of creating a roll stand in which even with small diameters and a relatively large center distance between the motor drive shafts Drive spindles can be provided, which with a large diffraction angle - and with a relatively short overall length - can be arranged, but still very high drive torques can be transmitted, for example for high-strength rolling Rolled goods and for rolling with large pass reductions.
- This construction is particularly space-saving and enables an optimal moment Dimensioning even with very narrow center distances of the rollers.
- Parts of the tooth couplings each have an angular position in the range between 0.5 and 1.5 °, preferably an angular position of about 0.8 °, maintained, the dimensioning of the Cardan shaft and also the toothed spindles can still be improved if the axes of the The tooth spindles diverge towards the drive motors.
- the toothed couplings expediently have spherical external toothings, whereby for The internal gears achieve axial mobility of the driven rollers of the toothed couplings extend in the axial direction over a multiple of the external toothing.
- the part that is movable relative to a roll is the Tooth coupling of the toothed spindle, which is connected to the cardan shaft, via a Compensation device to maintain a predetermined angular position on the foundation supported, the compensation device being designed as a lever system Parallel guidance is formed.
- FIG. 1 one Diagonal view and Fig. 2 a through the axes of the drive spindles Vertical section of a detail of FIG. 1 of an embodiment.
- the work rolls 1, 2, which have only a relatively small diameter 10, are each via its own drive spindle 11, 12 by means of its own drive motor 13, 14 drivable.
- the arrangement of the drive motors 13, 14 is such that the Center distance 15 of the drive shafts 16 of the drive motors 13, 14 is as small as possible.
- the drive spindles 11, 12 are arranged inclined to each other.
- each drive pin 4, 5 of the work rolls 1, 2 has a sleeve 17 rotatably connected, which has an internal toothing 18.
- This internal toothing 18th engages a spherical external toothing 19 on the outside on a further sleeve 20 is arranged a.
- the sleeves 17 and 20 thus each form a tooth coupling.
- the length the internal toothing 18 is many times longer than the teeth of the external toothing 19, so that axial mobility is possible.
- the work rolls 1, 2 in Axis direction to be moved relative to the roll stand 7. Different axial positions the work rolls 1, 2 are shown in Fig. 2.
- the sleeves 20 provided with the external toothing 19 are each non-rotatably on a spindle 21 and 22 mounted and together with this spindle 21 and 22 form a so-called Tooth spindle.
- the drive spindle 12 is the upper one Work roll 2 from the toothed spindle 20, 22 and an adjoining cardan shaft 23 formed on their universal joints 24 on the one hand with the toothed spindle 20, 22 and on the other is connected to the drive shaft 16 of the upper drive motor 14.
- Universal joints 24 could also be provided other articulated couplings for Transmission of high torques are suitable, for example flat pin couplings.
- the drive spindle 11 of the lower work roll 1 is up to the drive shaft 16 of the lower one Drive motor 13 rigid - if necessary in several parts - formed and with the Drive shaft 16 of the lower drive motor 13 coupled via a tooth coupling 24 '.
- the axis positions of the tooth spindles 20, 21 and 20, 22 are chosen so that their axes with the Axes of the associated work rolls 1, 2 an angle between 0.5 and 1.5 °, preferably include an angle of about 0.8 °.
- the in Roll stand 7 is only slightly adjustable, this is achieved by appropriate arrangement of the lower drive motor 13 reached; for the upper work roll 2 must comply with the optimal angular range, the toothed spindle 20, 22 by means of a parallel guide 25 trained compensation device against the foundation 26 are supported.
- the Parallel guide 25 is formed by an articulated lever system, etc. reach about vertically directed tabs 27 on an upper toothed spindle 20, 22 surrounding and opposite Toothed spindle 20, 22 on housing 29 supported by rotary bearing 28, which housing 29 is secured against rotation with respect to the foundation 26.
- the tabs 27 are each on one Angle lever 30 articulated, the knee joint 31 is rotatably supported on the foundation 26.
- the other lever arms 32 of the angle lever 30 are via a tensile or compressive force receiving tab 33 connected.
- the toothed spindle 20, 22 of the upper Work roll 2 adjusted together with this in the vertical direction parallel to itself are used, for example for setting differently high roll gaps 34.
- the inventive method succeeds Design of the roll stand, the universal joints 24 of the propeller shaft 23 despite being very small To dimension the diameter 10 of the work rolls 1, 2 very large, etc. as a result of Providing the tooth couplings 17, 20 and the tooth spindles 20, 21 and 20, 22.
- the arrangement of the toothed spindles 20, 21 and 20, 22 is made so that these in Direction to the drive motors 13, 14 diverge, which makes it possible that the Cardan shaft 23 with the toothed spindle 20, 22 connecting universal joint 24 with maximum Shape size. This is important in that the moment to be transmitted is different with the third power of the diameter of the universal joints 24 or the cardan shaft 23 enlarged. So it succeeds, despite the small diameter 10 of the work rolls 1, 2 and relatively close to the roll stand 7 adjacent arrangement of the drive motors 13, 14, a very transfer large torque, etc. a much higher than according to the state of the Technology, whereby an additional advantage is a torsionally rigid drive.
- Another advantage is obtained by installing a spring damper element designed as a spring cup 37 into the lever system of the parallel guide 25. This makes it dynamic forces acting on the roll pin as bending forces, caused by the Vertical accelerations of the drive train at the entry or exit of the rolling stock to one Fraction of conventional values reduced.
- the spring cup 37 can be on any Lever of the lever system can be provided.
- the spring-damper element is preferably adjustable depending on force.
